Finding the location of the EGR in my 97 concorde.

have a 97 Cirrus, 2.5L, box is black, near battery, sits on top of ECM/PCM which has wire harness plugs going into top. if not on top ECM should be next to it?

Here's a picture of your egr valve,located by firewall.Here's your iac.

I have the 97 built in 96' (non DFTE) and the EGR valves is just to the left of the Transmission dipstick.

• It's on the backside of the right head. To gain access to the EGR you will need to remove the airbox.. Then just a couple 8mm bolts to remove the vacuum hose off the EGR. The remove the two 13mm bolts that mount the EGR (from the back of the head). See diagram below.

• Hope this helps.

1. Make sure the fuel tank is 5/8 capacity or less before replacing or a fuel spill could result.
2. Disconnect negative battery cable.
3. Remove the rear lower seat cushion.
4. Push seat back and up to remove seat cushion.
5. Fold back the foam pad covering access cover for modules.
6. Remove plastic access covers from floor pan right side.
7. Disconnect the fuel supply line from module.
8. Mark the module orientation.
9. Drain fuel from right side of fuel tank. Lift module up enough to push hose into tank and drain. Do not spill fuel in interior of vehicle.
10. Pull module up and out of fuel tank.
11. Fuel Pressure regulator location.
12. Note location of ground wire tab location.
13. Remove ground wire.
14. Use a screwdriver and pry up on retaining clip.
15. Clip in the off position.
16. Fuel pressure regulator removed.
17. Remove O-ring from module.

• Reverse to install making sure to use all new O rings and clips and check for leaks post repair.

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using FixYa.

On my 97 concorde the water pump is behind the timing belt cover. You must first take the timing belt cover off to see the water pump.

On page 6-6, Hanes #72030, you will find the diagram that shows the EGR Valve for models 1981 through 1984.The diagram also is followed by models 1985 through 1997. The valve works exactly the same in the 1997 as it does in the 1984. If you need a diagram online, follow this link;

Exhaust Gas Recirculation System
Operation
This system reduces the amount of oxides of nitrogen (NO x ) in the exhaust by allowing a predetermined amount of exhaust gases to recirculate and dilute the incoming fuel/air mixture. The diluted air/fuel mixture reduces peak flame temperature during combustion, which in turn inhibits the production of Nitrogen oxides. The principal components of the system are:
- EGR tube (connects a passage in the intake manifold to the exhaust manifold)
- EGR valve
- Electronic EGR Transducer
- Vacuum hoses


Component and System Testing

1. Check the condition of all of the EGR system hoses and tubes for leaks, hardening or kinks on the rubber hoses. Repair and correct these conditions before proceeding any testing.
2. Be sure that the hoses at both of the EGR valve and EGR valve control are connected to the proper fittings.
3. Be sure the electrical connector is firmly attached at the valve control.
4. To check the EGR system operation, connect the DRB III scan tool or equivalent to the 16-way data link connector. The data link connector is located on the lower edge of the instrument panel near the steering column. Follow the scan tool instructions.
5. After checking the system with the DRB III scan tool, proceed to the EGR valve leak and control tests, then repair as necessary.

Removal & Installation
EGR Valve and Transducer



EGR valve and transducer assembly-3.5 engine




The EGR valve attaches to the back of the cylinder head-3.5L engine




Loosen, but do not remove, the EGR tube to intake manifold screws

The EGR valve attaches to the rear of the right cylinder head.

1. Remove the vacuum tube from the electric EGR transducer solenoid. Inspect the vacuum lines for cracking, poor seal due to hardness, or other problems. Replace with new hoses if necessary.
2. Remove the electrical connector from the solenoid.
3. Slide the transducer up and out of the mounting bracket.
4. Loosen, but do not remove, the EGR tube to the intake manifold screws.
5. Remove the EGR tube lower screws at the valve.
6. Remove the EGR valve and transducer.
7. Clean both gasket surfaces and check for any signs of leakage or cracks. Replace the components if any such damage is found or if the valve fails the tests.

To install:

1. Loosely install the EGR valve and a new gasket onto the cylinder head.
2. Using a new gasket, attach the EGR tube to the valve and tighten the screws to 95 inch lbs. (11 Nm).
3. Tighten the EGR tube to the intake manifold plenum screws to 16 ft. lbs. (22 Nm).
4. Tighten the EGR valve to the cylinder head screws to 16 ft. lbs. (22 Nm).
5. Reconnect the transducer solenoid to the vacuum fitting on the manifold.
6. Slide the transducer into the bracket.
7. Reconnect the vacuum lines and electrical wires to the EGR transducer.

all salvage yards have an "Interchange" book, it has that data, you can call your local salvage yard and ask what year models fit your car and they can tell you

Check your EGR valve and your IAC Idle Air Control valve make sure both are functioning correctly
